How do you find the length of two interesceting chords? - Answers

Before you even start calculating the solution to that exercise, the first thing to do is make sure that you understand exactly what you're looking for. As I read your question carefully, I'm not convinced yet that you know what's required. "The length of ..." means one single object, item, or drawing, and you've described at least two things ... the two chords, which, if they intersect, produce four pieces. What length are you looking for ? The length of one chord ? Of the other chord ? Of the short piece of one chord on one side of their intersection ? Of the long piece of the other one ? After you clearly understand what the question is, there's a step that usually helps when you're working with chords: Draw lines from the center of the circle to the ends of the chord. Each of those lines has the same length ... the radius of the circle. That often gives you some triangles in which you can find the lengths of unknown sides.
